Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed August 31,1904. Serial No. 222,952.

To aZZ whom, it may concern:

Be it known that I, J AMES J. HAROLD, a citizen of the United States ofAmerica, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements in MetalPiling, of which the following is a specification,reference being hadtherein to the accompanying drawings.

My invention relates to improvements in metallic piling as used insubway, foundation, and irrigation Work, dams, mine-shafts, caissons,sea-walls, locks, coifer-dams, retaining- Walls, and similar structures,and comprises flanged beams, preferably the channel-beam type,interlocked by coupling-plates having interlocking strips.

Referring to the accompanying drawings, Figure 1 is an end view of astraight run of my piling, showing the use of channel-beams; and Fig. 2is a perspective view of the same. Fig. 3 is an end view of'a straightrun of my piling,showing the use of beams having flanges on one side andinterlocking strips on the other side of the same face.

A represents beam members; B, the coupling-plates, and C theinterlocking strips engaging the flanges of the beam members In Fig. 3it will be observed that one of the flanges of each beam member D issubstituted by an interlocking strip, thereby avoiding the use ofcoupling-plates. Each strip is attached ing-angles rigidly mountedthereon, the respective edges of theweb-plate extending beyond the lineof the free hook edges of the angles.

2. In metal sheet-piling,a beam-section consisting of a flat web-plateand companion locking-angles rigidly mounted on and located adjacent tothe respective edges thereof,the bentaround hook edges of said anglesbeing set at angle other than a right angle.

3. In metal sheet-piling,a channel-beam section and a piling-sectionconsisting of a webplate and companion angles rigidly mounted thereonand provided with hook edges adapted to conform to and interlock withthe companion flanges on the channel-beams in assembling thepiling-sections in their alternate arrangement.

In testimony whereof I aflix my signature in presence of two witnesses.
